ADL5380: 400 to 6000 MHz Quadrature Demodulator
Product Description
Excellent quadrature accuracy is achieved using on-chip poly-phase filters for LO quadrature generation. Over a wide range of local oscillator (LO) levels, excellent demodulation accuracy is achieved with phase and amplitude balances < 0.25 dB and < 0.5°, respectively. The demodulated in-phase (I) and quadrature (Q) differential outputs are fully buffered. The ADL5380 provides a typical voltage conversion gain of 4 dB independent of differential load impedances as low as 100 Ω with a drive capability exceeding 2V pp in to 200 Ω.
The fully balanced design minimizes effects from 2nd order distortion. The leakage from the LO port to the RF port is <-60 dBc. Differential dc-offsets at the I and Q outputs are <10 mV. Both of these factors contribute to the excellent IIP2 of >60 dBm.
The ADL5380 operates off a 4.75V to 5.25V supply with a typical supply current of 200 mA. The ADL5380 is fabricated using Analog Devices’ advanced Silicon-Germanium bipolar process and is available in a 24-lead exposed paddle LFCSP package. Performance is specified over a -40°C to +85°C temperature range.
